SPECIFICATION formingpart of Letters Patent No. 573,366, dated December 15, 1896.

Application filed January 23, 1895. Serial No. 535,968. (No model.)

To all whom it may concern:

Be it known that 1, PAUL STARK, a subject of the King of Saxony, and aresident of Markneukirchcn, in the Kingdom of Saxony, German Empire, have invented a certain new and useful Improved Motor, of which the following is a full, clear, and exact description.

The present invention consists of a motor in which the power is derived from an eccentrioally-arranged rotary weighted body, as hereinafter more particularly described; and in order to make the present invention more easily intelligible reference is had to the accompanying drawings, in which similar letters of reference denote similar parts throughout both views. I

Figure 1 is a side elevation of the motor, and Fig. 2 a plan view of the same.

To the top of the stand A is attached a bearing 6, having a suitably-formed bearing surface for a ball 72, beneath which a bevelwheel pair a b is'mounted to rotate by means of the crank-handle c. To the ball 71- is rigidly attached an arm f, at the free end of which a weight g is fixed, and to the bevel a is rigidly attached an arm (I, which rests against said weight and when the bevel 1'0- tates causes the weight g to revolve. The arm f slants downwardly toward its weighted end, and at the lower part of the ball h is rig idly attached a downwardly-extendin g arm '21, connected by means of a loose ball-joint to the upper part 70 of an arm 70 n, at about the middle of which is fixed a ball Z, mounted in suitable bearings m of the frame A. The

lower part a of this rod is again connected by means of a ball-joint to a disk 9, rigidly I attached to a bevel q, gearing with a secondbevel r, mounted on a horizontal shaft carrying at its farther end the pulley 3. To the vertical shaft 25, on which is mounted the bevel q, is keyed a heavy fly wheel a. The arm 71 of the ball h is fixed to the latter in a position at right angles to the slanting arm f, while the center of the ball 1 is arranged vertically under the ball h, so that the arm 7t n will slant in the opposite direction to arm 1'.

The device operates in the following manner: On turning the crank c the bevel a, and with it the arm d, will be revolved, taking with them the weighted arm f g, the force of revolution of which is transmitted, by means of the balls h and Z and lever-arms i k n and disks p,to the bevel q, thence to the bevel r and pulley s. The heavy fly-wheel will equalize any unevenness in the running of the motor.

I claim as my invention- In a motor the combination of an eccentrioally-mounted weight, a ball h about which said weight revolves and an arm f to connect said ball and weight, a suitably-driven revolvin g pulley 19, an arm n mounted by means of a ball-joint eccentrioally on said pulley, a ball Z and extension 70 rigidly attached to said arm at, a machine-frame having suitable bearings for the said balls h and l and a lever t' fast 011 said ball h and means for connecting said lever to the end of the arm 7; substantially as described.

In witness whereof I hereunto set my hand in presence of two witnesses.
